DUMPING VEHICLE.

' Application flied February 17, 1922. semi Nm 537,187.

Tio all/whom t may] 'cof/wem# y Be it known that we, Harinas M. COLBY- sonY and FRANK JQMUMM, citizens of. the UnitedStates, residing at Minneapolisand St. Paulyin the counties ot' Hennepin and Ramsey, respectivelye and State ot Minnef sota, have invented certain new and useful Improvements in Dumping Vehicles and we do hereby dec-lare the following to be` a full, clear.. and lexact description ot the invention7 such as will enable others skilled in the art to which it appertains to. make and use the same. r y

Our present invention J relatesV to motorpropelled trucks having dumpingzor tilting. bodies, and has for its primary object to mount such'bodies lo'r'turning movement. ina horizontal plane, whereby the load therein, when the body is` tilted7V may be dumped at the .rear of the trucker at any pointl on eitheriside thereof.

With trucks now in use, it is necessary in delivering` coal, when the same must be discharged through a .hole in a sidewalk or unloaded and carried, to back the truck to the curb, which` is highly objectionable, especially .on narrow streets .or streets having carlines7 as .it materially interferes with the traffic. ln making such a delivery with a truck. .having our invention embodied therein7 it is onlynecessaryto stop the truck parallel 4vwith the .cujrhand then turn 'its body transversely thereto. in a .position to discharge its load 4over the sidewalk,Y This method of mounting atruck body is also. highly serviceable in road building orlin making lills asy it permits 'niaterials'tio be dumped over a `relatively largeV area Athus saying-a large amount' of handY shvovelling and at the saine time said materials may bex dumped where it will not. be necessary for the wheels of a truck to pass thereover.

To the above end, generally stated. the iiivention consists ot the novel devices andl combination of devices hereinafter described and defined inthe claims. y

In the accompanying drawings7 whichillustrate the invention, like characters indicate like pai-ts throughout the several views.

Referring to the drawings: Fig.` 1 is .a left-'side elevation of a motor# bodied therein; f

F ig. 3 is a fragmentary plan' view with:

some parts. sectioned .on the line 3-30f1 Fig. l; and y l? ig. 4 is a detail vie-w partly in elevation and partly in longitudinal vertical 5sectiontaken on the line 4-4 of Fig. 2,`on an enlarged scale.

Of Vthe parts of the truckproperl it'isl :importantt-o note theniain frame'` 57 front wheel .6, rear wheelr 7p engine-driven pro`V peller 'shaft 8, for .the traction wheels, cab

9 and body 1.0 ofthe type havinga rear l end. gate. The body 10 is. rigidly secured reary end of a supplemental truck trarne 13T to a frame 11, which is; hinged at 12fto'the thatv res/ts on and isfrigidly secured to a4 turntable ,14 carried by, the main 'truck Jiranien. As shown, the turntable,14V is in the Yform of a horizontally disposed annular body nie-inber having at its lower end aniv outstanding` endless track yrail or flange l15 mounted between upper and lower pairs of anti-.friction rollersY 16 and 17.y respectively. These rollersv .16 and 17 are journaled in brackets 18 rigidly secured to the main truck frame 5. The. lower rollers 17 sup` port the turntable. 14 and the upper 'rollers 16 prevent. the` same .from tipping under the tilting action of the body'lOQfand"which rollers 16 and 1'? also prevent binding of the turntable therebetween.

The turntable 14Y may be operatedfat will;V

either side thereof, by the following connec` spectively,V and which counter-shaft is pro# vided witha pinion QSthat is loosefthere'- on and meshes with a 'ring peller shaft 8,1 extends parallel thereto 'and is journaled in bearings 25. rigidly secured to thetmain truck vtrame Thefsprocket wheel V2() ig freetorotate jon thev 'shaft' and y A gear 24 'on the turntable14.v This ring gear 24. as shown,v is integral' withV the turntable 14 and lo` cated; in the vplane of the track rail 15. Thel counter-shaft 22'v is located 'above the pro` iop arranged for co-operation with a sliding half-clutch 27 keyed to the shaft 8 for r0' tation therewith. The sprocket -wheel 21 is keyed to the counter-shaft 22 and when the sprocket. wheel 20 is connected to the shaft 8 by the co-operating clutch members 26 and 27, said counter-shaft is driven from the propeller shaft 8. To drive the pinion 23 with the shaft 22 and thereby rotate the turntable 14, there is formed with the hub parts of this hydraulicY hoist, it is important to note the upright cylinderv 30, co

Voperating piston 31, lifting cablev 32, andr "i pump casing V33, in which isl mounted a rotor, the shaft of which is indicated by the numeral 34. The cylinder 30 is rigidly secured to the supplemental frame 13 for-v ward of the body 1O.g bviously, the cylinder 30 and piston31 afford ak vertically ad justable mast, yat the upper end of which is j a guide sheeve over'which runs` the liftate in all positions of the turntable.

ing cable 32.. One end of the lifting cable 32is attached to the lower end of a depend- "f ing arm 36 rigidly secured tothe front end of the body 10, and its other end is attached to an anchor bolt 37 secured inthe base of thecylinder 30. The liquid in the cylinder 29 is controlled, to project the piston 31 or permit the same to recede, by valves the controlling levers of which are indicated by the numeral 38.

To operate the rotor of the pump of the hydraulic4 hoist from theV counter-shaft 22, either simultaneously with the rotation of the turntableV 14 or independently thereof, the following connections are provided, to wit:

Loosely mounted onthe counter-shaft 22 but held against axial movement is abevel gear 39, which meshes with a bevel gear 40 keyed to the lower end of a vertical short shaft 41 having keyed to its upper end a bevel gear 42, which meshes with a bevel gear 43 Ykeyed to the rear end of ay long lhorizontal shaft 44, the forward end of which is attached to the shaft 34 of the pump rotor. The shaft 41 is located atv the axis of the turntable 14 to permit the drivingconnections to the pump rotor to oper Shaft41 is journaled in a pair of bearings 45 and46,the' former of which is integral with the Ybearing 25 and the latter of which is integral with a bearing 47 rigidly secured Said to the supplemental truck frame 13 and in which bearing the shaft 44 is journaled. nterposed in the shaft 44 are two universal joints 48, Formed with the hub of the Vbevel gear. 39 is a half-clutch .49 arranged To position the body 10 and then tilt thel same'todischarge the load at one side of the truck, the latch lever 51 fis manipulated to move the sliding half-clutch 27 into interlocking engagement with the half-clutch 26 andrthereby drive the counter-shaft 22 from the propeller shaft 8. The turntable 14- is then operated to move the body 1() tra-ns-y versely of the truck by manipulating the latch lever 52 tocarry the sliding halfclutch 29 into interlocking engagement with the half-clutch 28 andthereby connect the pinion 23, which meshes with the ring gear 24 on the turntable 14, to the counter-shaft. 22. After the truck body 10 has been properly positioned, the half-clutch 29 is moved out of interlocking engagement with the half-clutch 28 to stop the rota-tion of the turntable 14. The latch ylever 53 is thenmanipulated to move the half-clutch 50 into interlocking. engagement with the halfclutch 49 and thereby drive the shaft 34, of the rotor of the hydraulic hoist, through the connections 39 to 44, inclusive, and 48,130 project or elevate the piston 31 and thereby tilt thebody 10 and discharge its load therefrom. 1 y

To permit the operator of the truck to manipulate the valve controlling levers 38- of the hydraulic hoist,V cables 61 are attached to said levers and extended to the cabr 9. These cables 61 are extended over guide sheeves 62 and through the turntable 14 substantially at the axis thereof. By thus carryingthe cables 61 to the axis of the turntable there will be no slack therein during the various different adjustments of the body 10V in respect to the truck.

What we claim is:

1. A dumping truck comprising a chassis, a rotatable supporting frame, rollers carried bythe chassis, an annulus secured to the frame and travelling on ysaid rollers, a tiltable dumping body supportedby the frame, means for rota.ting-the frame, a mechanism for tilting said; body, said mechanism inoluding a-eable extending through said annulus Centrally thereof and travelling against sheaves carried by the rotatable f1-aine and the chassis.

2. A dumping truck comprising a horizontally rotatable structure including a tiltable vdumping body a chassis, superposed and interengaging bearing elements carried by said structure and Chassis, a sheave on one of said elements, a. sheave on said chassis, a cable for tilting said dumping body, said cable travelling against said shea-ves and extending through said elements Centrally thereof, and inea-ns for Winding up the cable to tilt said body.

3. In a truck having a inotordriven eleinent and an operators platform, the coinbination With a inain fra-nie, of asuppleinental frame, a turntable supporting the 20 supplemental frame from the main fraine, a
